Comment We will avoid it late and suddenly, or not at all (Score 1) 176

I don't think we should expect to see steady progress toward a climate solution, I think it's going to happen quite suddenly after some combination of the technology to do it getting cheap enough and the climate producing enough "shit's getting real" moments for a large fraction of the first-world population. At that point either we'll get our asses in gear and set up oceanic and atmospheric carbon sequestration megastructures all over the planet with maybe a little SRM sprinkled on top, or we'll be too distracted or impoverished to do anything about it for some silly reason or another and all the disastrous predictions will come true because this is a problem we're collectively too stupid as a species to solve. That's a real possibility.

The objective is to purchase "sustainable" aviation fuel, and thereby increase the demand for same.

That will require investment in the construction of additional capacity to create that fuel, unless there's a large surplus of unused fuel laying around somewhere. If there is, I'm not currently aware of it.

Comment It won't last. (Score 2) 40

'Carbon tax" generally faisl to stimulate a lot of investment in so-called renewable technology because there's no long term assurance that the tax will continue "forever". So an investment with a long term payback potential that could suddenly become a loser if the government changes or someone overhauls their tax policy has to provide a premium return to make investors take on the additional risk.
